The key on the top of the grip mount locks into a notch on the shoulder
of the barrel. With this feature the barrel is head spaced correctly and is easily
removed. With the grip mount removed, the barrel is unscrewed with only mild hand
pressure. This would have been a great feature to have had on the production guns.

With this design the entire gun can be disassembled into individual
parts in about ten minutes. This design is very simple and seems to have been a sturdy
design, judging by the wear and tear on the gun. With this design the gun has a rate of
fire of over 1500 rounds per minute. This would have been an interesting gun to fire.
